Detailed description of the invention
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
As shown in Figure 1 and 2, a kind of two-tube-pass coil pipe heat exchanger, comprise shell-side cylinder 4, left pipe box 1 and right pipe box 7, both sides, described shell-side cylinder 4 top are respectively equipped with shell side adapter 3, described shell-side cylinder 4 two ends are respectively arranged with left tube sheet 2 and trough of belt right tube plate 8, fixedly be equipped with the coiling of coiling outside core cylinder 10 between described left tube sheet 2 and trough of belt right tube plate 8 and restrain 5, described coiling tube bank 5 two ends are connected with right pipe box 7 with left pipe box 1 respectively; Described left pipe box 1 is provided with the flange be tightly connected by fastening bolt 6 and left tube sheet 2, and described right pipe box 7 is provided with the flange be tightly connected by fastening bolt 6 and trough of belt right tube plate 8; The dividing plate 72 its inner chamber being separated into upper and lower two individual cavity is horizontally set with in described right pipe box 7, described dividing plate 72 is sealed and matched with the septalium 12 on trough of belt right tube plate 8, described right pipe box 7 top is provided with tube side upper connecting tube 71, and described right pipe box 7 bottom is provided with tube side lower linking tube 73.
In the utility model embodiment, described core cylinder 10 right-hand member can be fixed on trough of belt right tube plate 8, but is not limited to this.Heat exchange tube hole number on described trough of belt right tube plate 8 is distributed in the both sides up and down of septalium 12 equably, and the pore position on described left tube sheet 2 is arranged identical with the pore on trough of belt right tube plate 8, and described left tube sheet 2 is without septalium 12.Above-mentioned tube sheet has considered the factors such as stringing number, pitch, the number of turns, tube pitch, ensure between each coil pipe, to keep original continuous print proportional spacing, lay out the position of septalium 12 in the pore region of septalium 12, thus achieve two-tube-pass by dividing plate 72.
